I These improvements relate to ventilation elements-forwalls and like structures, especiallyof brick or concrete, to providefor ventilati on through the walls, prevent moisture is pass ng up the walls, to sustain the II weight of tall walls when're'quired. My ele= ments WlllfOI'lIl a damp course, to allow of which an existing defective dampcourse, or

a mortar joint-or like suitable part of a wall 10 can be removed. I 1 I Another objectof the rvention is to enable theelernents to suit walls which have a vertical air ca-vity' between an outer and an innershelL a Y A further feature. of my preferred element is. an apertured front. plate or cover extend ing obliquely or vertically downward as weather guard,

Each element is of strong noncorrodible material, such as rustle'ss metal members I with, in some cases, bitumen filling some'of l the. spaces between the said members. I

The dimensions, shape, and minor details ofthe element-will bevarised to -suit the structure in which it is tov be used. 1

The drawings herewith wilhwi-th the following description, enable this inventionto be fully understood, .Minor details are variable at will from what is illustrated while retaining matter hereinafter claimed.

Figure 1 is a perspective view showing two elements spaced apart, parts ofv each front plate being-broken out. In this figure only one reinforcing bar is shown insertedin each element, and bitumen is shown in only one of the air spaces of each element, but in practice the number will not be limited to one in each case. A reinforcing bar is also shown ready for insertion as indicated by an arrow.

Figure 2 is a perspective view of a relatively high element, the height being due to the arrangement of the interior parts between the top and base plates ofthe element. The middle part of this figure is broken away to show the interior.

Figure?) is a partly sectional perspective view of a double wall, with one of my ventilation elements between courses of the wall shells.

The invention can be applied to a new wall while it is being built.

If a wall up which damp rises is'tobe treated to prevent such rise I select a horizontal joint usually near the building base, and I remove the mortar or cement there0fa few quire'd these projections are flattened, cut oil,

siredt o fill the ga -thus made, and will act .as spacm'g' members, and as the gap is extended more elements will be inserted. Parts of my elements will be below whateverver- T tical joint of the bricks or blocks extendupward from the elements, see Figure 3. I I I I term each element of upper plating 1, e5

lower plating 2', and 'iiiterniediateweight supporting means. Plates, 1 and aare united to one another, rivet 4 being suitable. The said means is for brevity-called hereiua riser, and one is shown. inFiures 1 and 2 formed by a corrugated metal s "eetor: sheets 3. In Figure 3, bars: 3 constitute theriser.

Thecerru ated. risers extend from front to back and iron'i end to end; of the element,

leave air spaces 3 e;t which some will be left open for ventilation, ironi irent to back of the element, butother spaceswill be filled when desired with damp-proof material such as bitumen, or will when desired be occupied byreinforcing bars 8-, which may 8'6 be of rustless metal. Rivets P, in Figure 2:

connect an: upper and a lower riser nienibrr.

. Figure 1 theend l otplatel, projects beyond the end 2 of plate 2, and the end 2 of plate 2 of the adjacent element projects beyond the end 1 of the plate 1 of the latter element; that is plate endsoverlap or break joint vertically when elements are butted tol gether or nearly so. The riser ends overlap adjacent shorter ends 2 and 1 of elements, and no damp will rise between the elements because the ends of the adjacent risers will overlap, or willnieet or nearly meet, and break joint vertically. I I

.Outer surfaces of he element are shown with means to facilitate lockingthe element in a wall. Thus 5 are projections of any suitable length to be embedded in grouting, con crete, or other wall material. When not re- I or omitted.

For each element front I provide an aperturecl plate shown vertical at 6, and oblique at 7 each plate having one or more lips by which to grip the element, and has any suitable ventilation apertures. Plate 6 is shown with an upper lip 6 and a. lower lip 6 and holes 6. The oblique plate 7 slopes outwardly and downwardly, and grips or is fixed on the element by means of a lip 7, and'in the preferred 1 10 ventilation.

corrugated metal spacing means interposed between and secured to said plates, the spaces formed by the corrugations of the spacing means affording air passages from one face to'the other of thevwalland between theupper and lower parts of the wall.

A Ventilation element having an upper and a lower metal plate, a corrugated metal sheet interposed betweenand fixed to said upper and lower plates to aflord air passages from end to end of the e1ement,and reinforcing bars disposed in certain of the corrugations. v a 1 4:.
